Answer

Spontaneous regression has been reported anecdotally in renal cell carcinoma. As many as 10% of patients with metastatic disease show no progression for more than 12 months. All systemic therapies are associated with treatment-related toxicity and low response; therefore, close observation is an option for asymptomatic metastatic disease. Once evidence of progression or symptoms appears, appropriate therapy should be initiated.
